Answer:
The E zone portion of the protein
Explanation:
The glucagon hormone which is a signal molecules that triggers a reaction in the liver cells is most likely to bind to the E zone extracellular portion of the G-protein-coupled receptor. This then changes the conformation of the receptor activating the heteromeric G proteins.
Answer:
two cells that have two identical copies of DNA
Explanation:
The options for this question are:
- Requires genetic variation
- Results in descent with modification
- Involves differential reproductive success
- All of the above
Answer:
<u><em>The correct option is d) All of the above</em></u>
Explanation:
The theory of natural selection explains that genetic variations occur in organisms of a species. Those organisms which are better adapted to live in an environment are able to survive and pass on their characteristics to their offsprings, hence descent with modification. Through this phenomenon, evolution takes place with the passage of time. Natural selection favours survival of the fittest. Hence, all of the above statements are true.
When placed in tap water, which is a hypotonic environment, animal cells have a higher solute concentration inside of the cell compared to the tap water. ... This, however, is not the case for plant cells which has a strategy to prevent lysis when put in a hypotonic environment. So the answer to your question is D
